Common Controls 7.0 are here--and they're crashing Excel - Microsoft Community

my organization received latest office 2016 update via current update channel.  looks mscomctl.ocx has been updated 7.0! it's been 6.x long can remember, pretty surprising major version update without kind of announcement.

unfortunately new treeview control crashes excel whenever tries display tooltip--i.e. whenever user mouses on truncated node text.  so our business-critical macro-enabled excel workbook pretty useless , users calling scalp.

help?

simple example here: https://www.dropbox.com/sh/kx8albvcpvaq7fq/aacq8s_ppf07fvhuvum7gp4_a?dl=0

edit add version of mscomctl.ocx in syswow64 directory still 6.1.  office seems have own local copy in %program files%\microsoft office\root\vfs\systemx86\.  if remove copy , replace version syswow64 works again.

hi andrew,

 

our engineering team actively working on fix. in meantime, can use following workaround options:

• rollback click-to-run build june release, version 1706 (build 8229.2073) or 16.0.8229.2073. see how revert earlier version of office 2016 click-to-run.

 

• if have existing copy of mscomctl in system32/syswow64 folder copy office folder below.

 

1. on 32-bit versions of windows: copy file c:\windows\system32\mscomctl.ocx c:\program files\microsoft office\root\vfs\systemx86\, overwrite newer copy of file older file.
2. on 64-bit versions of windows: copy file c:\windows\syswow64\mscomctl.ocx c:\program files (x86)\microsoft office\root\vfs\systemx86\, overwrite newer copy of file older file.

 

reference: office 2016 crashes when hovering on common control (mscomctl.ocx)

regards,

neha
