Internal Error 2503/2502

Anonymous

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

ONLY THIS WORKED FOR ME! IF SOMEONE STILL CANT UNINSTALL/INSTALL HERE IS MY TIP!!

Go to C:\ -> right-click the Windows folder -> Security tab -> Advanced -> Change the Owner to your username (your FOLDER name in C:\Users) -> Check Replace owner on subcontainers and objects -> OK -> Click Edit... -> Select Administrators -> Check Full control -> Select Trusted Installer too -> Check Full control -> OK -> OK

DONE! :)

I give you some pics to understand better:

This nasty little problem has raised it's head again on the latest Windows 10 update. Would like to add that this also works on the latest update. Thanks guys/gals, I was pulling my hair out trying to install an .msi.

Respect due!
