Error on launch (4.55.3) - SystemMissingFieldException

JCDCCSDS

I'm working in a Win2k8R2 vm (vmware workstation).

An old version of LINQPad used to work fine (can't remember version number, but may have been mid/late 2014). However I accidentally updated it and now it doesn't launch.

When launching, I get an error dialog, with System.MissingFieldException error. And when I expand the details, it says Field not found: 'ActiproBridge.TypeResolver.SmartTag'.

Nothing appears in the windows event log.

I've tried uninstalling and reinstalling LinqPad (deleting the LinqPad directories from AppData\Local & AppData\Roaming before installing).

Same version works happily on the host machine (Win8.1).

I presume you've not GACed LINQPad?

JCDCCSDS

LINQPad isn't in the GAC.

Is there any reason you don't want to run the latest version?

JCDCCSDS

No reason. Just that the latest versions (4.55.3 & 4.56.5 beta) errors on launch and I can't use it.

Nor can I seem to figure out what it's throwing that error. Guessing it can't find the assembly for SmartTag.

This gets weirder... I tracked down version 4.31 (from another VM that hasn't been run in ages) and it no longer works on this particular VM either

Trawling through my backups, I finally found 4.51.03. That works within the affected VM. Still puzzled as to why this is the only version that works there.
