Can Excel 32 bit instantiate ScriptMuuli 64 bit or PTV Visum 64 bit?
For PTV Visum yes, because PTV Visum runs as a 'out of process' COM server (*.exe), Excel VBA can instantiate both 32 bit and 64 bit Visum. This is different for the component ScriptMuuli, as this is an 'in-process' COM-server (*.dll): Excel 32 bit CAN ONLY instantiate ScriptMuuli 32 bit and CANNOT instantiate ScriptMuuli 64 bit. Workarounds: - Use Excel 64 bit to instantiate ScriptMuuli 64 bit (available with Microsoft Office 2010). - Visum 16/17: Register ScriptMuuli 32 bit. c:\Program Files\PTV Vision\PTV Visum 17\ScriptMuuli\Win32\ScriptMuuli.dll http://vision-traffic.ptvgroup.com/en-uk/training-support/support/ptv-visum/faqs/visfaq/show/VIS15643/ - Until Visum 16: install Visum 32 bit addditionally to be able to use ScriptMuuli 32 bit.
