I have the latest version of Pega Studio (8.0.2017.0) and facing this issue. Tried setting the Ouput Publisher to off and didnt work. Can someone help me with a solution?

Make sure you're running Studio as an admin and that you installed services as an admin.

This error occurred for the first time when using 2017 or 2018 version. Here is what I did and it worked.

1. Opened web adapter attached to the existing project.

2. Opened properties tab of web adapter via Object Explorer.

3. In Properties > Start and Stop, modified "BrowserBitness" from "Only32bit" to "Default".

4. Restarted my machine and it worked.

5. The next time when I added new web adapter, though the "BrowserBitness" had "Only32bit", both interrogation as well as Debug worked.

Hope this helps.

vivek, did this ever work on your machine or is this the first time you are trying to use the web adapter on this environment?
