I know this is an old thread, but its pretty much the only thing I can find on this issue.
In our company we story everything on dropbox, syncing both project files and source material to internal disks of our editors. We used to work solely on mac, which worked nicely. Now however we have one windows based PC and this is causing some issues with dropbox.
Saving a premiere pro file to the dropbox disk (which is local, but continually synced with dropbox) generates the ‘unknown error – please use ‘save as”. Saving to a non-synced location fixes this issue but this is far from desireable, since I will have to copy all project files manually back into dropbox.
Basically its a conflict who has the rights to write the files to the disk: premiere trying to save its files or dropbox trying to keep everything in sync – at least, thats how i figure it.
Is there anyone with a solid fix for this issue, perhaps giving premiere more permissions/rights over dropbox or something?
It would help tremendously.
ps: using win 7 64bit (hoping maybe win10 solves this issue)
