@Martijn Berger (juicyfruit) can you check installer to be sure it does have and install that dll, just in case?

@seghier khaled (seghier) please try to re-download and install the RC, could be some corrupted installer or something maybe…

the problem that when i installed it i didn't see folder called : 2.77 ; just 2.76
so i uninstalled the old version and reinstall again and it work now
but that never happened before
link of the installer :

Uuuh… would mean MSI installer does not handle correctly update of existing installation?

yes he seems to imply that.
Ill need to create some kvm images to test these interactions in a controlled way

@Martijn Berger (juicyfruit), any news?

We didn't get any other reports on this though, I guess we would have if this happened to others. If others do have the same issue, we should probably assign a higher priority however.

hello ; i installed the new version 2.77 rc2 but already the rc1 installed
i don't know if the problem still exist or no

No update in months, we would be flooded with reports if it still exists.


I have 2.78; it may be that i did not extract all files in the .zip folder using WinRAR.

Sorry if this is the wrong place to post this comment but a web search landed me on this page.

I am currently having a related problem - although I am not sure it is for different reasons to the original poster.

I was getting the same "Python35.dll missing" error and then I noticed that when I unzip a version of Blender from 'latest builds' my virus protection (Norton) deletes the following files...
as soon as I unzip the directory.

The current release version (has different python-35.dll) does not have this problem.

Further, the last time I tried to use a 'latest build' version was in November (different python35.dll) which did not (and does not I have rechecked) have this problem when I unzip it.

Anyway I thought it might be helpful information - but sorry if I am wasting anyone's time.

Should have said I am using Windows 10 - 5820K - GTX 970

Just did install/repair/uninstal/instal/repair and I keep hitting the same wall. I don't speek tech, so that was where my ideas ended.
I googled the issue and this was top hit, so hope it's still checked on a new post.
