How do I resolve Error 2738 when installing AvaTax for QuickBooks?

Environment

QuickBooks 

Resolution

  • This is actually a Microsoft error and not specific to AvaTax. It has been reported to happen during install of many QuickBooks related application, and is due to the vbscript.dll. not being registered. Please see the following steps to resolve:

 

  • Open a command line window as Administrator, which requires clicking Start typing cmd in the search box, then right-clicking on the cmd.exe program and choosing Run as Administrator.
    • Next, paste the following in the command line and hit enter.
    • reg delete "HKCU\SOFTWARE\Classes\Wow6432Node\CLSID{B54F3741-5B07-11CF-A4B0-00AA004A55E8}" /f

That previous command removes the incorrect entry for VBScript support on 64-bit Windows 7.

  • Next, you need to make sure VBScript is properly registered by typing:
    • c:\windows\syswow64\regsvr32 vbscript.dll
    • or simply regsvr32 vbscript.dll if you are already in the syswow64 directory.
