Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I can't open projects in UE4

Hi all,

First time posting here and have just bought/subscribed to UE4 . I've got a small problem though when attempting to open the sample project, and the same when trying to open a new project. The highly helpful error message doesn't give me anything but the following :

We apologize for the inconvenience. Please send this crash report to help improve our software.

alt text

I don't suppose anyone else has got this problem/knows of it and is willing to help ?


On a side note, the UDK is still opening up fine.

Edit : Just found this going through the log files, any ideas?

Doesn't seem to have worked unfortunately, now it's bringing it up as soon as I press the launch button (so even earlier) :(.

Just a quick add on to this that my CPU and RAM are no where near at maximum usage when the program itself crashes according to task manager.

Here's a pastebin of the error log :


Any help would be appreciated.

Sure thing, specs of the PC I'm trying to install it on :

Quad core Intel i5 3570K 3.4GHz


Geforce GTX 460 (Bit outdated I know but I've just carried it across from an old build while I save for something a bit higher up)

Windows 7

I know this is a tad under spec but I've seen people running with much worse specs than this (onboard graphics) so am at least expecting the program to open?

I seem to be meeting some problems reinstalling visual studio after it messed up on me now and it's telling me I get a cryptographic error which I can't solve, could this be linked in any way?
