I basically went back to using Vegas 19 Build 550 that is stable for both editing and rendering after trying to live with V20 (214). However, I get the update notice with this build. Is there a way to disable it?
Yes, that worked (renaming install.cfg) - Thank you... V19(550) no longer prompts to update.
Yesterday, I did an edit with four stacked video tracks (see image below) and had no issues editing or rendering (several times) with Vegas Pro 19 (*550), but it froze when I tried to render it with V20 (214). While V20 has some additional features it seems a step back in stability (for some users).
* Vegas 19 had subsequent updates to what I refer to as beta 20 (636, 643).
Worked for me too. But I noticed an issue. Renaming the cfg file causes the help menu option "Deactivate the software on this PC" to not work. Doing it the way @RogerS suggests solved that problem. Might also avoid a problem down the road when Vegas tries to call home for a license check.
After the feedback (thanks), I deleted the update URL listed in install.cfg (instead of renaming the file) and retagged the "solution" to this post. It successfully eliminated the update available message at startup.
