During running my installation I get the error message

Error 1723. There is a problem with this windows Installer package. A dll required for this install to complete could not be run. ...

LOG FILE contains the information that

Wdsfpca_CleanupFiles of the Library C:\WINNT\Installer\MSI3C9.tmp could not be executed or loaded.

Repairing the installation of InstallShield Developer did not solve the problem. What should I do?

Thank you !
