I have seen there are other topics very similar where we can't install due to "installer has insufficient privelages to modify this file:\.....\TBDCAF5.tmp" error message and rolls back installation. It won't uninstall through the uninstall tool, it won't allow me to manually delete the BD2010 folder as I don't have the privelage even when administrator.
I have sent the sysdump file to the moderator here Alex via private message but so far no response. This appears to be a common problem maybe a thread on here by the moderator telling us all what the problem is and how to fix it rather than fixing one at a time, and me running my PC now for 5 days with no virus protection.
Not happy, please help!
