The CTC format was deprecated back at VS2008. Yes, there is a converter
available from convert from CTC to VSCT. Covered by this MSDN page. Read the page for instructions, I'll
just outline that page here. You need to obtain the Perl runtime. Then
you can run the ConvertCTCToVSCT.pl script located in the
VisualStudioIntegrationToolsin subdirectory from the command line:
c:pathtoperl.exe "c:pathtoConvertCTCtoVSCT.pl" PkgCmd.ctc
Where pathto are the paths to the respective files.
