Re: [Vstgui-devel] Windows 7 issue (for some)

[Vladimír T. <vl...@au...>]

Hi Howard,
we used to have similar problem with our plugins when we moved to VS2012
and it is quite possible you have the same problem. It was caused by old
Direct2D libraries in customer's Win7 while the build machine and all of
our testings PCs had the latest versions. And we also did not specify
the _WIN32_WINNT macro...
We have discussed it with Arne, check this thread:
https://sourceforge.net/p/vstgui/mailman/message/34125599/
It has been successfully fixed in the sources, please check your
d2dbitmap.cpp source.

The Windows update with new Direct2D libraries that also fixes the
problem is KB2670838.

Hope this will help you.

Best regards,
Vladimír

> We received a report that one of our VST3 plug-ins (VST 3.6, with VSTGUI 4) is not showing its GUI in Windows 7 Professional. I switched back to that old OS and I see the same problem. But our tech support guy, who is using Windows 7 Ultimate Edition, is able to load the plug-in fine (this is in Cubase 7.5).

Processing seems to be taking place with no errors, and I can adjust the automatable parameters and see that they are working as expected. But the GUI does not show up

Does VST3 or VSTGUI4 make use of some updates that might not be present in systems that have not been updated? (I’m going to try updating my system, but that could take a couple of days, considering how long it’s been… assuming updates still work at all for Win7). Meanwhile… any thoughts?
