Some quotes from IRC:
<Golkombie> I'll answer your forum questions right here.
<Golkombie> 1. I downloaded MegaGlest directly from the MG website.
<Golkombie> And its the latest version
<Golkombie> 2. I am using Windows Vista Home Premium Service pack 2
<Golkombie> 3. My graphics card is Mobile Intel(R) 4 series Express Chipset Family
<Golkombie> Processor Pentium(R) Dual-Core CPU T4200 @ 2.00GHz, 2000 Mhz, 2 Core(s), 2 Logical Processor(s)
<Golkombie> 2GHZ, 3 GB, 32 bit
<Golkombie> Other 3d games do work, but I play them on Unity 3d
<Golkombie> It says I cannot support glActiveTexture (OpenGL 1.) or the ARB_multitexture extention
<Golkombie> Open GL 1.3*

<MGBot> Title: Intel® Driver Update Utility (at www.intel.com)
<Golkombie> I downloaded that a while ago
<Golkombie> I installed all the recommended drivers
<Golkombie> The same result appears.
<tomreyn> so when you start the game, it doesn't fail immediatley you said?
<Golkombie> yep
<Golkombie> The intro starts
<Golkombie> but it crashes within the next few moments.
<tomreyn> and if you skip the intro it crashes immediately right?
<Golkombie> Yes
<tomreyn> in C:\Documents and Settings\[User name]\Application Data\Roaming\megaglest you should have a glestuser.ini file
<tomreyn> [User name] would be your windows user name
<Golkombie> This is the location: C:\Users\William\AppData\Roaming\megaglest
<tomreyn> then delete everything in it and replace it by the block of preformatted text below the screenshot here: https://docs.megaglest.org/MG/FAQ#My_video_performance_is_bad.2C_what_can_I_do.3F
<tomreyn> that's indeed a driver issue then
<tomreyn> https://docs.megaglest.org/MG/FAQ#I_get_an_error_stating_MegaGlest_needs_an_OpenGL_version_of_at_least_1.3_to_work
<MGBot> Title: MG/FAQ - MegaGlest (at docs.megaglest.org)
<tomreyn> you could also try that first option but i think we already ruled that out
<tomreyn> how did you install MG? you said you have it on your desktop, or is it just the icon there
<Golkombie> everything is on desktop
<Golkombie> ran the installer but selected a custom installation folder
<Golkombie> I'm going to reinstall
Summing it up:
Windows Vista 32-bit with a 2009 "Pentium" mobile CPU + internal Intel graphics - newer than mine (which work) I think. Error message seems to be the one about OpenGL incompatible drivers.
A screen shot of the actual error message would be good to have. It could be uploaded to imgur.com or similar.
