My first post here as I am at my wits end.
Did a new install of my FSX on my desktop computer. It was never on there before. The installation went well and I then attempted to install my old PMDG 737 and also some old scenery and schedule files. So that messed it up and I decided to start a fresh installation of FSX and that is where I the installation now refuses to complete.

The installation is done on a clean drive E:\ Nothing else is on that drive.
Just before the end of disk 2 the error message comes up " E:\FS\Licenses\client-issuance-ppd.xms-ms and the message appears "Please insert the disk". and that then prevents the finalisation of the installation.

I have been at it for 3 days now. Things I have done. Cleaned every and anything in my C drive and in the registry that contains FSX or FlightSimulator or MS FlightSim. Ran CCleaner. downloaded and ran the MS KB928080. Created a new Admin user to try and install it via that new user.; all without success.

Short of formatting the PC and starting from scratch, I think I have tried everything that has been suggested in the various similar posts.

Where else can I look or what other registry do I need check/change?

I also followed these instructions:
1. Run regedit (Windowskey +R)
2. Expand the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\CLASS\{4D36E967-E325-11CE-BFC1-08002BE10318}
3. After you find the folder, double-click Upperfilters on the right side.
4 . Change the value from 0 to PartMgr and then click OK. If PartMgr is already there, then leave it as is.
5. Close Registry Editor

Trust that there may be something vital that I have overlooked.
