The COM-based custom tools, which were built from C#, VB, VB.net, VC.net. ect, will crash on SR1.
The COM interface was changed in SR1 and is not compatible with SR0 or older version anymore.
Suggestion: Rebuild the EXE file of custom tool for SR1 users with steps below
1. Run Origin 2017 SR1 as Admin, close it.
2. In Visual Studio open the corresponding *.sln file like SendNumericDataToWks.sln.
3. Rebuild it.
4. Try the rebuilt exe again to connect to Origin 2017 SR1.
