PME2024 Newtonsoft error

[RobD]

I recently updated to PME2024. Everything worked fine for more than 2 months, but when I opened Vista and Designer today, I got the attached error message.

Application Internal Error. Application will close. Could not load file or assembly 'Newtonsoft.Json, version=6.0.0.0, Culture=neurtral, publickeytoken=xxxxxxxxxxxxxxxx' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (exception from HRESULT: 0x80131040)

I googled this error, but I only got some Does anyone know how to solve this issue?

@RobD I suggest to check if by chance any files were removed from the PME folders. The quickest way to do this is to run the Diagnostic Tool on the machine selecting "List of Files" option.
And if you have a copy of diagnostic from the version before upgrade you can compare the folder side-by-side.
