I have the same issue. It fails after the extacts are done and then indicates it can’t find the log to display what happened during the process. I checked the directory specified by BRD2ODB_TMP but it is not there either.
Has anyone had success using v10 of odb_inside?
I had this error message too and then it would not open ODB++ UI window, instead it export uncompressed ODB++ files (files with extension .out) . OrCad tech support had no idea. I attempted to run brd2odb.exe (in folder ODB++_Inside_Cadence_Allegro) by itself but it gave a error message of missing msvcp120.dll. I found a tip to fix this dll file from https://answers.microsoft.com/en-us/windows/forum/windows_7-performance/missing-msvcp120dll-file/f0a14d55-73f0-4a21-879e-1cbacf05e906?auth=1, and installed both 32-bit and 64-bit of Microsoft visual C++ Redistributable package. After rebooting my PC, it worked. Latest version of OBD++ Inside I just installed was 101 (ODB++_Inside_Cadence_Allegro_101_Windows_64_SA_Setup.exe). Hope this helps if you had the same problem.
