How to ensure installer will work on Win98?

[John P.]

Hi.

I have a few installers which install some custom made textures into a game.

The installers work perfectly on WinXP.

The game in question does not officially support Win98(SE), only WinXP and Win2K.
So I thought everything would be OK with these installers.

But now it turns out that the game community have been able to "hack" the game so that it will play just fine on Win98, and that's when some problems started.

Because apparently, some of my installers won't work on Win98.
The weird thing to me is, that the most 'advanced' installer, where I use things like checking the registry to see if this and that file has already been installed, and write to and read from HKCU, which as far as I know isn't even a part of Win98 registry, works(although with a lot of error messages - but it does the job regardless, according to 'customers') while the 'simpler' installers does not work, according to 'customers'.

I have no way of checking. Well - actually I still have a Win98 CD laying around, but I'm not going to start dual booting just for this.

I have attached the 'simpler' installer .nsi below.

I've tried to remove the "real names", and made it as simple as possible. So it's not the installer script, but an example with the same commands.

Could it be as simple as the fact that I'm using $WINDIR for the icon?
Something else like that that won't work on Win98?


[edit]I see now that there are a couple of small redundant things, like I never use the VER_NAME, but that's something that's "left behind" from the bigger, more 'advanced' script, and in any event shouldn't be the reason for this problem.[/edit]
