[ERROR] Prototype Preview does not work


As of 1.11.2021, my prototyping preview has stopped working. Once I click on the “Play” arrow, my browser loads up the following error message:

File not found

Firefox is unable to find the file in the directory /C:/Users/User/AppData/Local/Icons8/Lunacy/Prototyping/0d53f87c-1d6a-450f-8677-10144644102b/index.html

It seems that Lunacy is unable to generate the html file. The directory under AppData does not exist either.
I have tried this with different project files and different content - the result is the same. Reinstallation of the software did not help either. Any ideas?

Hi there! What version of Lunacy do you use, the MS Store one or the one downloaded directly from our website? The former has a bug that affects prototype preview. We’re working on the fix already. Meanwhile, we suggest installing the version from our website: Lunacy – Free Design Software for Win, Mac, Linux

Thanks! Your website version does work indeed, the MS Store one is broken.
It seems you have also gone to a browser based preview, cool!

The topic can be closed, thanks again!
