How to change the default help file in AutoCAD 2011?

[Ahankhah]

I recently downloaded AutoCAD help in chm format from this address: http://images.autodesk.com/adsk/files/autocad2011chmhelp.zip. Althogh I decompressed the above downloaded zip file and changed AutoCAD's config to use acad181.chm as help reference, I was unsuccessful:(.

Any idea to resolve the problem:?:

It sounds like you didn't read the instructions carefully.

 

Instructions:

 

1. Download the AutoCAD2011CHMHelp.zip to your local drive (such as My Documents\AutoCAD2011Help).

2. Extract the zip file to this same folder.

3. To access the CHM Help, you’ll need to click on acad181.chm or create a desktop shortcut.

It should work but I am a bit worried about the directory naming using (help) may be causing problems I would make it help-acad there are a number of characters that you should never use in a file name, in particular any in the top row of your keyboard
