ReadRegStr - what's wrong

Hello Guys,
i'm new and excuse me for me english, i'm austrian.

I tried for a couple of days and search here in the forum and in the FAQ and in the documents, but i haven't found an solution.

I will install a addon for a Program. The program is existing installed on the pc's from the users. But i don't know, in which location. Under c:\programme oder d
:\program files and so one.

Now i have see the ReadRegStr but i become an error:

Error: command ReadRegStr not valid outside section or function

My lines are here:

ReadRegStr $0 HKLM "SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\9.0" "EXE Path"
StrCpy $0 $INSTDIR ""

In the EXE Path (this is a String) there i will find the correct path to the application.

And in this path i will installe my file, as the same folder structure. Does this go? I have search and tried, but i have no idea what's wrong.

And the next was in my script:

OutFile setup.exe
InstallDir $INSTDIR
.....
SetOutPath "$INSTDIR $0"
File "..\Microsoft Games\Flig

I know, any user will say, i should search in the forum, but believe me, i have search for a long time.

Seeming i'm too stupid.
🙄

I hope everyone can help me.

Do you have a "Section" in your installer? Many functions only work between "Section" and "SectionEnd".

example:

Section "my program" SEC01

  ReadRegStr $0 HKLM "SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\9.0" "EXE Path"

  StrCpy $INSTDIR $0

  SetOutPath "$INSTDIR"

  File ""..\Microsoft Games\Flig

.

Yes i have a section. Here are the lines.

I have this install file create with Venis IX the Free Version.

I had been editing my post as you posted that. Does the example above help a little?

Hello,
the error message is now away, i can compile and test, but i can't see the destination Folder.

The installer can't presumably read the string. Hhmm.... i will make a littel screenshot for this string in the registry.

Should you know "Installe Creator" from Clickteam? With this installer that's work, but this installer have no enough functions.

Here is the screenshot:

Move the following lines into your section:

ReadRegStr $0 HKLM "SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\9.0" "EXE Path"
StrCpy $0 $INSTDIR ""

I have this line in the section, but i can't see any Destination path. 🙁

Get rid of the StrCpy line.

Yiippppiiiee, that's it! Wow... it's great.
Many thanks for your help.

I 've sitting about 3 days for this problem... 🧟 but, i think, this was not the only. 😉

Also thanks. What a great helpfully forum.👍
