Vista 32 vs 64

[BigGuy]

Hi,
My company has upgraded an older program for Windows XP and Vista, but it still uses the old style help files tha Vista cant read. Microsoft has 2 files that adds back the capabilities of reading these help files. However one is 32 bit and the other is 64 bit. How can I dynamicly find out what the users system is 32 or 64? This will allow me to include a condition for installing the appropriate file. Additionally how can I check if their Vista has allready installed this feature?

Hi BigGuy,

You can determine whether or not the operating system is 64-bit by using the System.Is64BitOS() action.

As far as determining whether or not feature you are referring to is installed or now I'm not sure. Perhaps look at registry keys that are changed or added; or the versions of files that are installed.

If I correctly remember, HTML Help Workshop (free help authoring tool from Microsoft) can import & convert old help projects (.hlp) to the new format (which generates a .chm file).
Not sure how good is the conversion, but if the result is OK it's maybe better to convert your help to .chm instead of installing files to support the long outdated .hlp format

I would imagine something like this.

if (System.Is64BitOS()) then
  -- 64bit :)
else
  -- 32bit :)

Unfortianatly the software is looking for the old file and not the newer help file format, and since the programming firm has exceded the budget twice it has been determined to not change it.
