Win-10 64-bit, installed Lazarus ver 2.0.10. Laz can't find FPC source dir.
JohnHerbster:
The instructions said that by far the easiest way to install Lazarus was to DL and run the proper EXE. I tried that and allowed it to delete my old Lazarus. Then it needed new FPC update, so I did that (ver 3.2.0) and let it delete the old FPC. After it finished, I tried running Lazarus and it says that now it needs the FPC sources from $(LazarusDir)fpc\$(FPCVer)\source. The comment box says
"Directory: C:\Program_Files\Lazarus\1.8\fpc\3.2.0\source\
"Error: directory not found
"You can download FPC and the FPC sources from
"http://sourceforge.net/projects/lazarus/?source=directory.
I cannot find any such folder in that location or anywhere else.
All suggestions will be appreciated. This morning I had a working, albeit old, IDE. Now I have none!
Peter H:
Some months ago I had a similar case.
Remove all traces of fpc Lazarus and fpc related environment variables and reinstall; this should fix it.
wp:
Whenever I install a new Lazarus version I always do this as a "secondary installation" and use a new directory for the Lazarus user settings. This way the new installation can coexist together with the old one, and I always can switch back if something goes wrong.
I think it is the second page of the installer where you can check the "secondary installation" box. Later you are asked about a folder for the config settings - this should be a new directory without any old config files (I name it c:\laz-configs\laz<version>_fpc<version>). Do not register any files with Windows to open on a double-click, because with multiple installations there is a high chance that the registered version will open the wrong IDE.
To fix your current mess, I agree that it is probably the fastest option when you really delete the old Lazarus folder and its config folder (by default it is in c:\users\<your name>\appdata\local\Lazarus), and reinstall a-new.

Thanks Peter H and WP,
* I uninstalled both FPC and Lazarus and manually cleaned up folders and regedit of leftover stuff.
* Reinstalled FPC first, then Lazarus into C: root. Tried out Compile on blank form and got 5 warnings and about 515 hints. * Ran and stopped the *.exe w/o errors.
* Added “Hello World” and it compiled w/o any more warnings or hints and ran w/o any errors.
I think that perhaps they do not run well when installed in a "Program_Files" folder.
I will think about pursuing that secondary installation idea next time.
Thanks again. --JohnH

This sounds strange. The standard installer for Windows has its own FPC in the package, so there is no need to install FPC separately.

Absolutely true. Never install into "c:\Program files". Access to this folder is restricted.
