Hi guys, I tried to do the above on 3 different machine each with a different OS and if i either try manually in regedit, it is saying i access denied when i try make a new key i get the error cannot create key: error writting to the registry. I get more or less the same error on each comp. I have tried on Vista X86 with UAC disabled, WinXP SP2 and Win2k3 machines. I also tried importing from a reg file and i get a similar error saying cant import: error accessing registry. I am just wondering how you ( brandilton ) managed to do this. I have tried lots of different things from logging into safe mode and i have tried changing the permission before inserting or importing but this one is still managing to allude me. Any help will be much appreciated as i getting really p***ed with all the Apps of mine that dont work in Vista and/or dont have working Vista versions. Cheers,
