User editable install directory - help!

RigorMortis · 18th January 2009, 04:29

From the subject you would assume I'm an idiot - but let's assume I'm not for a minute.

This installer is for a map pack which must be placed in a very specific directory to function. I found some code to extract the correct directory from the registry/filesystem, but it only functions inside of "section" and thus I cannot use "Page directory" to let people edit the directory if it happens to be wrong.

My question is: Is there a way to allow a user to modify a variable created inside of "Section," and if so, how can I do this?

Any help would be appreciated.

read from the registry in .oninit and put the result in $instdir

I tried that, but unfortunately the install directory doesn't auto-populate with the supposed-correct directory... which is bad.

I'm unfortunately very new to NSIS and will probably be fighting with this until I give up and just don't use an installer... lol. This thing has been driving me nuts for weeks.

...What does that mean, exactly? If you StrCpy $INSTDIR in .onInit, the directory page will enter that value into the path field as the default. Unless you change the contents of $INSTDIR again at a later time.

Perhaps looking at the script you can see what I've done wrong?

looks like you've got the code to copy the dynamic Steam Account-generated folder to $INSTDIR in your section? you should put that StrCpy in .onInit after calling - and verifying the output from - Call GetSteamAccountName. ( actually, after the "gogogo:" label - no point in doing any code that may not actually get used.
