Hi HomerJ,

According to KM03793071, this is a known issue related to a Microsoft file and the resolution is as follows:


  • If version of the pdm.dll is found on your computer, the setup program will recgonize this during installation and will instruct you download the corrected DLL from the Microsoft site.


  • To debug GUI tests in UFT One, ensure that you have the most recent version of the pdm.dll file installed and registered.

The pdm.dll file is installed and registered with Microsoft Visual Studio and Microsoft Office, and installed (but not registered) with Microsoft Internet Explorer.


  • If your currently registered version is lower than 9:


- Uninstall the Microsoft Script Debugger (if installed).


- Perform a repair installation of Microsoft Visual Studio or Microsoft Office.

- Check the registry for pdm.dll version: HKEY_CLASSES_ROOTCLSID{78A51822-51F4-11D0-8F20-00805F2CD064}InprocServer32


  • If you need to use the pdm.dll file installed with Microsoft Internet Explorer, do the following:

1- Ensure that you have administrator privelgest.
2- Locate the pdm.dll file, usually located either in c:program files(x86)internet explorer or c:program filesinternet explorer.
3- Move the pdm.dll file and the msdbg2.dll file from the same folder to a different location.
4- Run the following commands:

regsvr32 <full path to pdm.dll>pdm.dll

regsvr32 <full path to pdm.dll>msdbg2.dll


Following those instructions will allow the file to be replaced and the new file installed and registered.


Hope this helps,
