Error in EnvVarUpdate.nsh after upgrading to v3

I've upgraded to v3.05 as I was getting some odd results with v2.x (it would hang on some systems even though it was run inside a docker container).

I'm now getting the following error:

Error: unterminated string parsing line at macro:_IncludeStrFunction1:7

Error in macro _IncludeStrFunction1 on macroline 7

!include: error in script: "EnvVarUpdate.nsh" on line 49

Error in script "/artifacts/build/windows/MyProgrm.nsi" on line 65 -- aborting creation process

I get the same issue from lines 50 and 51 in EnvVarUpdate.nsh

Any ideas on how to correct or at least how to debug a bit more? I'm new to NSIS. MyProgrm.nsi was written by someone else and I'm picking it up...

Cheers,

Jesse
