Cura 2.5< starts once 2.5> does not start

[ejwind 0]

Cura untill 2.5 installs and starts (but only once) I can slice with no problems, print 7 files with Ender 3. But every time I cluse Cura I need to reinstall to open it.

Cura above 2.5 will install but will not open. windows shows the bussy symbol for 5 seconds and nothing happens.

 

My system:

Acer Laptop with Windows 7 Home premium SP1 64bit Intel Core i7 Q 740 @1.73Ghz 16 Gb RAM ATI MoObility Radeon HD5850

 

Cura Log File from Roaming:

Can someone help me? I tried Slic3r but I don't like the software (yet)

 

With kind regards,

The log file shows Cura failing when detecting the OpenGL version. Newer versions of Cura tend to require newer versions of OpenGL.

Update the drivers for your video card and see if that solves your problem.

ATI HD-5850 drivers

Goodday CarloK,

 

Thank you for your reply, I allready checked the drivers when I saw the log, only did the windows "check for update" and it said that I allready had the last drivers. I clicked on the link in your reply and dl and installed the appropiate file..........it works now!! Thank your very much, back to slicing and printing!
