I first recommend you trying to uninstall Vegas from control panel as it will remove all of the files completely leaving no trace of it behind that may interrupt next install/re-install process

If however Vegas cannot be found in the section above, your next best option is to type Vegas in the windows search and look at every possible path and location the program could be in

You'll be deleting the folder named "VEGAS" in Program Files.

If the folder is not there, that means VEGAS has been removed unless you forgot to empty your recycling bin.

If this still doesn't work, then it means there's still traces of Vegas left somewhere in your system meaning you'll have to go and look through whatever there is left from either MAGIX, Sony, or VEGAS and you'll have to delete every piece of file there is.

Don't worry as you won't have to delete your Project files since they don't affect it.

Usually when I encounter a .DLL problem with Vegas or any other Application/Executable I would just remove/uninstall every part of the software and re-install it again. If the Dynamic Link Library file wasn't found then this is either a location unknown problem where the program can't identify where the Library file is, the installer simply skipped past it, or the file could've been corrupted.

If however the error is consistent, then I just install it straight off the internet through https://www.dll-files.com/

Also don't mind me, I kind of like giving the most options possible for problems that occur if I know them. Some of my responses get long some times ^^'

@HyperionZ
I did read your signature and I'm curious which versions of Vegas Pro software you have and which one you are using at the moment. Can you tell us?

That's your choice. But when advising others on an open forum who may or may not have your level of experience, it is always best to offer the least destructive advice first, lest your suggestions create more harm than good to another's system. That is my first responsibility as a field engineer and corporate technical trainer of fifty years.

"Should" such advice seem advisable after gathering all of the relevant information, I would precede it with a number of cautious warnings, starting with a full system and application backup, having all serial numbers and registrations at hand first, and then using the appropriate tools at hand, which in this case, are here:

As far as blindly sniffing out every registry entry and leftover file from a previous Vegas installation, you are obviously more determined and astute at editing the registry than me, and I can't for the life of me imagine how I would feel if my advice resulted in a new user being left with a crippled system and without a lifeline.

Those responsibilities are the things I look at first, before laying my broad wisdom and sage advice on the hapless. Welcome to the forum.
