YES!!! Assuming I have the same issue.
My installation would hang at roughly that time, sometimes a little later. The big text box would sort of go empty and then slightly resize itself back and forth, very quickly. The scrollbars would jump around.
I opened the Wine debugger and kept seeing references to this "CoolSBSubclass". Google suggested it was to do with "Cool Scrollbars", probably a scrollbar library. I thought maybe if I changed the text box size it could avoid triggering the bug. I couldn't find a way to force-change the window size, but then I had another idea.
Here's the workaround that worked for me:
- run "wine regedit"
- navigate to HKEY_CURRENT_CONFIG\Software\Fonts
- Set font size to quite large or quite small
- 48 and 120 worked for me, 96 is default (**DECIMAL**)
- run installer
- run regedit again and set font size back to 96
