Resolving "Run-time error '-2146232799 (80131621)': Could not create Acctivate business logic object: New ACCTivateApp.ComInterop Automation error when installing or updating Acctivate.

If you're receiving this runtime error, that typically means Acctivate on the server was installed in a new location instead of the location Acctivate was previously on. This article applies to versions before 12.2.

To fix "Run-time error '-2146232799 (80131621)': Could not create Acctivate business logic object: New ACCTivateApp.ComInterop Automation error, we recommend re-installing Acctivate on the workstation. 

Workstation are pointed to the AcctivateData share for versions prior to 12.2, so during the installation, you'll want to navigate to the "AcctivateData" share on the server. If you've recently changed server, or reinstalled Acctivate on a server to a new location, you'll need to point the workstation to the new server. 

The location of the AcctivateData share should be \\ServerName\AcctivateData

If you did NOT recently update or change servers, but you're still receiving the error on a workstation, you can try changing the AcctivateData location in the Acctivate.exe config file. You can do that by following these steps:

1. In windows, navigate to the Acctivate directory in program files. By default, that's located at C:\Program Files (x86)\Acctivate
2. Open the "Acctivate.exe" config file (located directly below the normal Acctivate.exe shortcut.) You'll know it's the right file because "Type" will be "CONFIG File."
   1. You may get a warning from windows that it cannot open the file. If that happens, choose the option to run with another program and choose notepad.
3.  Ensure that under the <appSettings> header, you have the following line: <add key="AcctivateDataPath" value="\\ServerName\AcctivateData" /> where ServerName is replaced with the name of your server.
   1. Your config file should look like this:
      1. 
4. Save the file and try running Acctivate again.

Please Note: You may receive a warning about not being able to save the file to that location. If that happens take these steps:

1. Save the config file to the Desktop.
2. Delete the existing Config file in the directory.
3. Copy the config file from the Desktop into the Acctivate directory (C:\Program Files (x86)\Acctivate)

Now the config file will be updated.
