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

This is something that i found out by doing something else

Open "Task Manager" (Ctrl+Shift+Esc or right click the start bar and click: "Task Manager")

Click "Processes" Tab

Right click: "Windows Explorer"

Click: "End Task"

Click "File" on the top of the windows

Then Click "New Task"

Type "explorer.exe" without quotations

Check the "Create this task with administrative privileges" box

Now install/uninstall your app
