I have uninstalled Agent many times and restarted the PC and also given full control permission to the folder but still unable to install VSE 220.127.116.119. Windows giving error "don't have appropriate permission to access the item"
There is no real information to work on with this..
Is D: a mapped drive or a CD/DVDrom?
It would be better for the purposes of this test to copy the installation folder to the local machine. Please copy the folder to your desktop and re-run the setupVSE.exe and see if this will now install.
