I would first try uninstall / reinstall again, but uninstall using a third-party uninstaller that can remove left-over registry entries and other pertinent data the default uninstall leaves behind, which in usually the root of recurring issues Revo Uninstall and Geek Uninstall are two that have pro and freeware versions.
If that does not work, try creating a new folder without the words VST and move all VST plug-ins to a non-VST folder. If SF launches successfully, replace a few at time to I.D. the offender. Note, it may take some IDing the offender.
Some VST files (.dll) may be in the Steinberg folder or another folder named "VST" in Program files and Program files (x86).
Or.. you can also request support directly from Magix.
There is most likely one VST plug-in that is stopping SF from fully launching. , it may indicate during the scan which one is hanging. Do you have any third-part VSTs installed?
Otherwise, If you can copy and post the text from the "vst_grovel.log" file, that may indicate the offender. I recall that <.log> file is in -username> AppData> Local> Magix and/or SOUND FORGE folders> You can try deleting it as well.. it should re-build next time you launch (or attempt to launch) SF Audio Studio . btw, 'AppData' is a normally hidden system folder
The first of them seems to be suggesting a problem with \msvcr90.dll, which is a system file, not a specifically SF file. IOW, it is saying there seems to be a problem with your Windows installation, not necessarily with SF itself.
Second, what happens if you tick the box "autoskip plugins after 10 seconds"?
