I've checked some websites and found out that Adept PublishWave PlugIn comes in different versions and for each version, there are certain requirements.
For example, version 2017 requires the following:
- Adept Desktop Client 2015 (version 10.0) or later Required
- Microsoft .NET Framework 4.6.1 Required
- Supported Operating Systems
Windows 7 32/64-bit editions, Windows 8.0/8.1 32/64-bit editions, Windows 10 32/64-bit editions.
The problems with the plugin might be related to compatibility with the operating system, lack or 3rd party add-on corruption, virus infection, etc.
