Win 7 Ult 64-bit:
On random installs i get the above error msg w/ 1 of the 2 codes listed..... here is what i have done:
-Checked Windows Installer, it is set to manual
-cleared out all those install files
-tried to locate the reg files used to correct this similar issue on previous versions on Wins, no luck on that
I am pretty computer literate(minor repair as a hobby, build my own machine/family machines), but since about the time wins 7 came out I have had little time to really dig into wins 7, so have been restricted to mostly a user the last 6 months or so. I have reached the extent of my knowledge on correcting this particular issue.
oh, and to add.... I tried to install and run the windows clean up utility and it gives the same error while in setup =D
