Text file changes for registry files that include path statements

This code here should get you through.... and I assume you have a Basic MSI project type.

[CODE]export prototype set_prop(HWND);

function set_prop(hMSI)

STRING tmpINSTALLDIR;
STRING svInstalldir[256];
NUMBER nBuffer;

begin

tmpINSTALLDIR = INSTALLDIR;
nBuffer = 256;
StrRemoveLastSlash(tmpINSTALLDIR);
MsiSetProperty(hMSI,"DOUBLE_INSTALLDIR",tmpINSTALLDIR);

end;[/CODE]

Thanks.

I will try it.

Do I need another new property though to store the final value in?

Or do I change this: Session.Property("DOUBLE_INSTALLDIR") = Replace( Session.Property("INSTALLDIRNOTRAIL"), "\", "\\" )

To this: Session.Property("DOUBLE_INSTALLDIR") = Replace( Session.Property("DOUBLE_INSTALLDIR"), "\", "\\" )

Nope not necessary ... you can still have one property DOUBLE_INSTALLDIR and perform all the actions (remove the trailing slash, remove double slash) on it.

Well, that didnt work either.

I keep getting the attached error when running the .MSI.



It is referencing my custom action which has this code: Session.Property("DOUBLE_INSTALLDIR") = Replace( Session.Property("DOUBLE_INSTALLDIR"), "\", "\\" )

But that did work when the replace statement was replacing just INSTALLDIR.

LOL...

Appears to be a problem with the custom action sequence.


1: Run the InstallScript Custom action and result is DOUBLE_INSTALLDIR property is loaded with INSTALLDIR value without trailing slash.
2: Run your custom action which does "\\" to "\" on DOUBLE_INSTALLDIR property

Yea, that is what I am doing:

[rrinblue22]

you can also just write one single VBScript which performs both task of removing the trailing slash and "\\" to "\".
just a suggestion to un-complicate things 🙂

Well..

Now I am closer than ever before.

Now it is kind of working, however, my config file ends up with two rows:

Thank you for all the help though. I am now almost there.

I guess in the XML Editor I can add a remove line to remove the bad one? Not sure why I should have to do that though.

I have just sent an email to your RatBoyGL account here.
