Can't Install V7.5 on Windows 7 Pro PC

Hi

Every time I try to install V7.5 explorer.exe crashes at startup reporting a problem with sldwinshellextu.dll.

I have to uninstall TLB in safe mode, I can then reinstall my previous copy of V7.1 OK.

Any idea what's causing the problem?

Hi

I have updated the PC in question to Windows 10 Pro and also updated the Nvidia Quadro Video driver to the latest version but still no success.

After installing 7.5 and restarting the PC the display just alternates between the screen wallpaper and a black screen with no icons showing, the only way out is to power down the computer. From the lock screen I can then make a system restore to my prior setup with TLB 7.1 which works OK.

Don't know where to go from here?

Regards
Barry
