Compile/Convert Project with Updated Engine - Never Works

[Vaei]

If I ever install an upgraded version of UE4 the conversion never works. I have to make a new project, re-import everything, etc. Takes ages.

Why is the feature there if it doesn't ever work? Even basic/new projects fail.

You might want to try removing the "Read Only" flag from your binaries.

They aren't read only.

Edit:

I changed read-only to off already but didn't check after - it keeps turning back on. :/

[Vaei]

Right, so, anyone know how to fix this?

I have the same problem, I thought it was just me being a source code noob. Maybe it's both of us being a source code noob. Who knows!

Definitely put this in the feedback forum and answerhub when you get the chance. If you tag it "bug report" they'll put it in their pocket to look into.

Well that's weird. Perforce requires files to be read-only by default, so it might be a bug in UE4's perforce management... Though it shouldn't really matter if you don't have perforce to begin with.

I'll do it, but I'm not entirely sure what to put exactly. Can't convert because of error in OP and unable to set read only flags off? Or is the last part not important?

PS: Very likely that we're both source code noobs.

Yeah, I can't disable them. I thought it was the desktop.ini file staying read-only due to being a system file but using the command 'attrib -r -s C:/UE4/Path /S /D' did no better. Edit: NM doesn't have one there.

Edit2:

None of the files are read only. But the folders say items within are read only even at the lowest level??

I'm having this problem too, when upgrading from 4.5 to 4.6. My Project builds fine in VS2013, but doing the upgrade from the ue4 launcher fails.
