Prerequisites Condition - Help needed plz

[danieluc]

Hi,

I want to set a prerequisite to be installed only on certain operating systems, thus i use the condition of the prerequisite depending on the operating system.
My problem is that I want some kind of OR between the conditions; more exactly

XP SP2 and Vista are accepted.

Can anyone give me a hint on how to do this ?

Thanks,
Daniell

Can you be more specific what do you need? What kind of OR condition do you need?

Can you give an example?

[danieluc]

Well I need the prerequisites to install in case one of the two OS are found:
Windows XPSP2 OR Vista, and I dunno how to specify those both.

Thanks

You can use this condition :

((VersionNT = 501 and ServicePackLevel > 1) OR (VersionNT = 600))

Hope, this is what you needed..

Thanks for your reply,
I am allready using this condition for my CA, but I want to put this condition when installing the redists. Can i do something like this ?

I have not faced this situation, i m not sure about whether we can use this for redists!!!

[danieluc]

This is why I was saying I need an OR between the redists conditions 🙂
I'm still searching for a sollution 😞
Thanks,
Daniel

Unlike the rest of the conditions on prerequisites, OS conditions are considered as a list of supported platforms and are automatically OR'd together. After all, it's hard to imagine a single machine is both Windows 2000 and Windows XP simultaneously.

[danieluc]

That would be cool 🙂
I guess you are right, an AND condition between OS wouldn't be of any help to nobody. But if there is another condition, I expect it would do something like

(OS1 OR OS2) AND COND1

Is this correct ?

Cheers,

You're correct. The prerequisite is installed on the target machine if the target machine meets any of the operating system conditions and all of the other conditions that are listed on the Conditions tab in the Prerequisite Editor.

Just managed to implement and test it on both operating systems (and win2k to see that it works). Thanks a lot for your help; my problem is solved. 🙂
