Hi all,

Wondered if someone could help?

I have upgraded two machines to Win 10 over the past few days. Both installations went fine initially, except that on one machine, after coming out of Outlook I then couldn't restart the app - it said something like I didn't have the correct permissions to access the pst file. I thought it might have something to do with different user accounts so I therefore decided to do a fresh install from USB and all has been fine since.

The other machine had an initial problem with sending emails which was sorted by the sfc /scannow command. However, I now wanted to reinstall Zonealarm - I had thought that it was still installed; it shows up under Programs and Features but doesn't show up in Task Manager or have the usual icon in the taskbar etc...

The version that would be installed (from Windows 8.1) wouldn't work anyway, but when I try and install the correct version I get "Unable to create an installation log for logging installation activities". I also get the same error message when trying to uninstall the previous version of Zonealarm or use their Clean.exe program. A google search for this doesn't seem to shed too much light on it.

I have a feeling it may be a similar issue to the first machine, as installing Zonealarm on that machine has completed fine, but I didn't really want to do a fresh install on the second machine having got it all set up how I want it.

As mentioned I have a feeling it may have something to do with user accounts - which seem to be different in Windows 10 compared to before, but didn't know where to start on rectifying it.

If anyone has any suggestions they would be appreciated.

Many thanks
