Hi Support Team,
I recognized that my vitual store has a file called ActionStudioMRU.ini in C:\Users<myuser>\AppData\Local\VirtualStore\ProgramData\VSoft\FinalBuilder8.
This indicates that FinalBuilder 8 has saved ActionStudioMRU.ini to the folder C:\ProgramData\VSoft\FinalBuilder8 and thanks to windows UAC it has been redirected to the virtual store.
You should consider to add write access to C:\ProgramData\VSoft\FinalBuilder8 during FinalBuilder Setup.
Best regards
Michael
