    Flexnet ISUSPM.exe - how to remove?

    I installed a trial of Naturally Speaking and it automatically installed ISUSPM (Flexnet software updater) on my new Windows 10 PC. I can't figure out how to remove it because it doesn't show up under Windows uninstaller or other uninstaller programs. I see ISUSPM.exe pop up when starting my PC and I want this thing gone. Here are the file locations:

    Program Files (x86)\Common Files\InstallShield\Update\ISUSPM.exe

    Program Files (x86)\Common Files\InstallShield\UpdateService\_isusres.dll
    Program Files (x86)\Common Files\InstallShield\UpdateService\agent.exe


    To be more confusing, there's also ProgramData\Installshield\Update\isuspm.ini. This is listed in autoruns as "Optimize Thumbnail cache Files". There are no other files in this folder.

    If I click on agent.exe in ProgramData\FLEXnet\Connect\11\, it runs "FLEXnet Connect Agent (32-bit) in the task manager.

    If I click on agent.exe in Program Files (x86)\Common Files\InstallShield\UpdateService\, it runs "Macrovision Software manager Agent (32-bit) in the task manager.

    Both files show dates as having been installed or updated tonight when I installed Naturally Speaking.

    I found a tool that supposdekly lets me uninstall this. Here are the instructions:

    1 Download the FlexNet Connect Software Manager Uninstall program from the Flexera Software website.

    2 Click the "Start" button Windows and select "All Programs." Click on the "FlexNet Software Manager" to start the application

    3 Click on the "Settings" button in the window that appears. Change the frequency of the automated update checks to "Manually" for the "Critical" and "Important" updates.

    4 Run the FlexNet Connect Software Manager Uninstall program to remove the FlexNet Connect Software Manager registry-key settings.

    5 Press "Alt." Ctrl" and "Delete" on your keyboard, and click on "Start Task Manager." Click "isuspm.exe" from the list and click the "End Process" button.

    6 Browse to "c:\program files\common files\installshield\updateservice" in the Windows Explorer window, press the "Delete" key and click the "OK" button to remove the FlexNet Connect Software Manager from your computer.

    So I did everything except step 6. It says I can just delete the UpdateService" folder. Okay, but it only contains 2 files. ISUSPM is actually in the other folder (Program Files (x86)\Common Files\InstallShield\Update\). Plus it's also in ProgramData\FLEXnet\Connect\11\. So I'm very confused. What can I do to remove all of this. Why does Program Files (x86)\Common Files\InstallShield\UpdateService\agent.exe run the Macrovision Software manager Agent? I don't want to remove something I shouldn't. If I run ISUSPM.exe from the Common Files folder, it tries to connect to the internet but then doesn't seem to run the software. It's like some files are already deleted or missing (Elsewhere I've read that tool only removes certain versions - maybe that's what the uninstall tool did, and left other versions behind?). The instructions don't mention anything about the Program Files\FLEXnet folder. I have no idea now if other software that relied on ISUSPM are affected. If I run ISUSPM from the ProgramData/FLEXnet folder, it runs the software updater program, which lists Naturally Speaking but nothing else.

    What do I do to get rid of all this? I could try uninstalling Naturally speaking but I'd like to leave it installed for now.

    Any help with this Installshield ISUSMPM mess?

    I uninstalled Naturally Speaking and that left only 1 file remaining in the ProgramData\FLEXnet\Connect\11\ folder - products.fnc-xml. So I just deleted the FLEXnet folder in ProgramData. So I'm guessing whatever FLEXnet is it won't be bothering me again.

    That left me with:

    Program Files (x86)\Common Files\InstallShield\Update\ISUSPM.exe

    Program Files (x86)\Common Files\InstallShield\UpdateService\_isusres.dll
    Program Files (x86)\Common Files\InstallShield\UpdateService\agent.exe


    I just moved those files out into a backup location just in case. Now in the Program Files (x86)\Common Files\InstallShield\ folder there are 3 other folders with files inside that I didn't touch:


    I don't know what those are so I'm leaving them alone. I'm afraid somewhere in here now I may have made a mess moving and deleting these Installshield files. There was a scheduled task calling ISUSPM to run "Optimize Thumbnail Cache Files". No idea what that is and I can't find anything at all about it or if it was part of Windows scheduled tasks or if it was put there by something else. I deleted it because it called upon ISUSPM. Does anyone know what that is? Naturally speaking made a mess out of my new PC with all this Installshield ISUSPM garbage, and it doesn't help that it's in multiple places. I sure hope I didn't mess things up on my new PC already trying to get rid of this junk.

    Impact of FLEXnet Connect being installed along side unrelated apps

    With respect to rivre's post on details of program location and function, my approach is more focused on system impact and performance degradation. His post points to additional component executions in alt. locations created by a totally different vendor. Rely on both posts and consider we obviously do not cover the component comprehensively or exclusively. Had this app been destructive, I would have invested more time analyzing it.

    Observation: The program(s) & scripts are benign but waste time & resources at boot & program startup after the initial installation and updates successfully complete. The programs occupy 3.3MB + 2.2MB of space, but if authentication is successful, a 60.1MB backup occurs. For no more than its functionality, the package wastes a huge amount of the registry with backup keys @ hive HKCR, HKCU, HKLM & HKUs .DEFAULT, S-1-5-18, S-1-19 & inconsequential MUIs in S-1-5-21s.

    ID: Corel Roxio VHS to DVD 3 v3.0.1 dated 5/23/2014 hardware/software solution.
    Also installed
    C:\ProgramData\FLEXnet\Connect\11\Agent.exe, .\ISDM.exe, .\issch.exe & .\ISUSPM.exe;
    C:\ProgramData\Macrovision\FLEXnet Connect\11\Agent.exe;
    C:\Program Files (x86)\Common Files\Sonic Shared\*
    C:\Program Files (x86)\Common Files\InstallShield\UpdateService\Agent.exe
    C:\Program Files (x86)\Common Files\PX Storage Engine\???
    (v11.0, 11.5 & 12.1.1 signed by Flexera Software @ http://consumer.flexerasoftware.com.com; dated 5/21/2010). It calls to the Vendor Authentication Server @ http://updateservice.sonic.com/ [most likely expired redir http://qawebw1.roxio.com/registratio...stration.jhtml, http://activation.roxio.com/activateme/, & http://activation.sonic.com/activateme/; caution, curiosity killed the cat; there are remote scripts loaded to the local pc. We don't know how they react outside the installer shell] to update the Roxio VideoWaveVHS component. If you have registered with Corel/Roxio, you should be prompted for your name/password, however if your software is not registered, the script terminates with a failure code.

    In the final analysis, why would you bother to register software acquired by another Corp(Corel) that was released in 2010(Roxio)? It results in a nominal impact on storage space. The major impact on system performance is the registry entries, primarily Classes & CLSID. Each time Any program uses stored information in the registry, it must search the entire hive(s). Registry size is a Major factor in system startup, changing users, and program initialization. This set of programs also affect bandwidth, be it Ethernet or Wi-Fi.

    Recommendation: On all products developed or released by Roxio, 2006 and after, are likely to deploy this less expensive method of registration and program patches. CREATE A SYSTEM RESTORE POINT! Install applications as usual and insure you go to the "Help" menu to "Check for updates". After each run, exit the application and rerun until application reports it is up-to-date, you "have the latest version/release installed" or "no updates available" (typical responses) close & CREATE A SYSTEM RESTORE POINT!

    Once completed, open & leave application running. This will prevent any shared/Common [files] from being inadvertently uninstalled. I do not trust InstallShield to delete residual files and obsolete registry keys. InstallShield is dependent upon the vendor's instruction set to remove selective files. It does not necessarily restore the system & file system to its prior state. Alright, lets cut to the chase...use an uninstallation tool that scowlers the registry for those unassociated values. Popular examples are IObit Uninstaller v7+, Piriform CCleaner v5.5+, and Wise Program Uninstaller v2+. I endorse none, but caution they include destructive processes. Insure you have backups of your Program dirs & ProgramData. Uninstall FLEXnet & reboot.
