I did not like the message indicating that projects created in an older version of TestComplete needed to be converted and would no longer be usable in older versions of TestComplete. I wonder why this is necessary going from TC 9.0.1312 to 9.10.1894?
TestComplete 9.10.1894 failed to recognize the first object selected in our application and failed. I simply executed it again, and it is currently running with no further issues.
I also executed a standalone script to restore a database using MS SQL Management Studio. TestComplete 9.10 could not find the smss.exe executable using the new isatallation. I changed the relative path generated by TC 9.0.1312 to the "C:\Program Files\..." path for smss.exe, and it ran fine. Apparently, the installation path for 9.10 executables is different than 9.0.
