R Tools > Data Science Settings... --> Error in R Interactive window - An exception was encountered while constructing the content of this frame.

I am using VS 2017 Community Edition - Version 15.6.6 - upgraded from version 15.6.5. Installed RTVS and in Visual Studio when R Tools > Data Science Settings... is selected, I got this message in the R Interactive window:

An exception was encountered while constructing the content of this frame. This information is also logged in "C:\Users\v-joberc\AppData\Roaming\Microsoft\VisualStudio\15.0_0ffa9891\ActivityLog.xml".

Please help to fix this issue. TIA.

Add that right now. Guess issue is incompatibility with (maybe more recent) R client. I uninstall R client (3.4.4 I think), uninstalled Visual Studio and reinstalled it to use R client version coming with Data Science solution (3.3.2). Then it worked.

No, it is unrelated to R. Could you locate and send us your privateregistry.bin which should be in

C:\Users[USERNAME]\AppData\Local\Microsoft\VisualStudio\15.0**** Associated log files would help too

mikhaila AT microsoft

Thanks

privateregistry.zip Uploaded .bin file (in a zip file). Please advise where to find the associated logs files.

Thanks John Berchmans

Log files are usually next to it, such as privateregistry.bin.LOG?

[OscarTex]

I did not find any such file in the C:\Users\\AppData\Local\Microsoft\VisualStudio\15.0_0ffa9891 folder as well as other folders under that.

Just letting all know we found the problem and we will try and get the fix into the nearest VS update.

Closing, expected in 15.7.3 and 15.8.3

Hi!! I am facing same issue. Is there any other way around on the solution or we have to wait until next VS update?
