andreachrist,
Welcome to SevenForums.

Reboot.

Boot into safe mode.
Now try to run the installer.

Ø Power down your computer.
Ø Power up your computer.
Ø IMMEDIATELY—Start tapping the SPACEBAR
Ø When the Windows Boot Manager screen appears,
Press the F8 key
Ø The Advanced Boot Options screen will appear.
Ø Using the down arrow key, highlight Safe Mode
Ø Press the ENTER key.

In shorthand,
PowerUp | Spacebar until Windows Boot Manager
| F8 | Safe Mode | ENTER

thanks for reply, but how do i run the installer in the safe mode?

thanks again

You boot into Safe Mode.
Then you install the program.

thanks again but that is not working.
i am going to report to the guy who installed our computer.

thanks anyway

Sounds like a good plan.

For what it is worth; MS has a couple of KB entries on how to solve InstallShield problems. These are searchable, but do not expect too much, they did not help me. SAFE MODE did not either.
