Hi,

I have an installer that can be installed only on some operating system:
1.Windows Server 2003
2.Windows XP
3.Windows 2000
.
Now before doing installation, I want to check whether the system fulfill the minimum requirement :
Pentium 3 733MHz, 128 MB RAM(256 recommended) and 100 MB Free disk space.

Is it possible to do this checking using InstallShield and prompt error message and finish execution if requirement failed?

I really need your help.
Thanks a lot.

Hi agustina,


you can try the following........


For problem with your operating systems you can choose condition
"VersionNT>=500"

To check for requirements you can try to write a custom action!

The MHz you can read in registry under:

"HkeyLocalMachine\HARDWARE\\DESCRIPTION\\System\\CentralProcessor\0"

For "Ram" try function GetSystemInfo(EXTENDEDMEMORY,nvResult,svResult);


surely not the best way but possibly it helps

MSI provides a table "LaunchCondition" to test those kinds of requirements.

In ISX, you can set your conditions in "general information" -> "Product properties" -> "install conditions"!

ex : for the RAM requirement (128 MB), set the condition : PhysicalMemory>=128, and give the message that will appear if the condition is not fullfilled.

I must admit i didn't find the conditions for the processor speed or the disk space, but the necessary disk space is already checked by msi, so don't care too much about this one.
There is still the property "Intel" that gives you the numeric processor level, for example 4 for 486, 5 for P5, 6 for P6, etc.

Wish you good luck and hope it was useful
