I have installed GXRS10.2-138 with Delphi 10.2 installed (10.2 is the only Delphi version) and found Grep won't run; see attached error message.
It seems it looks very hard for all versions of GExpertsRS.dll EXCEPT GExpertsRS102.dll. I made a copy of GExpertsRS102.dll and gave it the name GExpertsRS101.dll and it works now.
Thank you for your work with GExperts!
Already fixed in svn revision 2077 (2017-06-14).
If you need it, check out the sources and compile \projects\standalone\grep
thanks!
