Ok so i've been having this Problem now and i'm sure i'm not the only one! If you have Doom builder 1.68 on Windows Vista or any other Computer for that matter you might have this Error Message occour:
Invalid call or argument Procedure or somthing like that.
The thing is Explorer.exe causes the Problem so what you are going to end doing is this:
Step 1. Open Doom builder, to where it is onscreen.
Step 2. Open Task manager with doombuilder right behind it.
Step 3. Go to Process and find Explorer.exe
Step 4. End Explorer.exe, The button is at the bottom right of the Task manager screen.
Step 5. With Explorer.exe closed, your entire Desktop's Icons, Start menu, and all the regamaro will be gone but don't Panic cause you can re-open it which i will add at the bottom. Your Doom builder should be on screen now but dont close or minimalize it or you will have to re do the Procedure.
And that Wraps that part up, but now i will tell you how to Re-open
How to Re-open Explorer.exe:
Step 1. Very simple, very simple indeed. Just open up your Task manager again by pressing and holding down "ctrl", "Alt" and " Delete" Buttons.
Step 2. When it opens go to the Applications Tab at the top of the Task manager screen.
Step 3. At the Bottom right of the Task manager screen there are 3 buttons:
1. End Task
2. Switch to... (Switch to Task)
3. New Task
Click the 3rd button New Task and type in Explorer.exe, and your Stuff will be restored safely.
Anything at the bottom bar will NOT be erased or anything.If you are downloading somthing it will still be there!
May your gaming Experiences be great, my Brothers of the Gaming world.
