Attempting to register the version 9.1.0 AcuToNet.dll assembly using:

  regasm20acu.exe /register /codebase AcuToNet.dll

Gives this error:

RegAsm : error RA0000 : Failed to load 'C:\Program Files (x86)\Micro Focus\Acucbl910\AcuGT\bin\AcuToNet.dll' because it is not a valid .NET assembly


In version 9.1.0 the AcuToNet.dll is a .Net version 4 assembly so the regasm20acu.exe will not work.

There is a new version attached to this article, regasm40acu.exe which will successfully register the AcuToNet.dll assembly in version 9.1.0. 

Download and extract it to the 9.1.0 bin directory, then execute:

  regasm40acu.exe /register /codebase AcuToNet.dll
