Issue switching between version 3.* and 4.*

I have been using 4.093 "PCH" for a while with no problems. I have some older code that I would like to make some changes to and compile with 3.249. I reload the old compiler, try to compile and I get this error
Error: The selected compiler: "PCM" is not installed on this PC. First off I am not using the PCM compiler (I am using the PCH). Second I have done this before and had no issue. I tried placing the 3.249 in another folder and get the same error. Anyone have a clue as to what is happening? I would really like to compile this in 3.249.

Thanks,

Doug

I would try a re-install of the 3.249

First rename folder that holds 4.xx to PICC_new

Then reinstall 3.249 I think it will put it in c:\program files\PICC

Then try to re-compile. You didn't say if your using the IDE.
I just use the command line compile.

I switch compiler versions all the time and have no problems.
But, I had some problems when the path to the compiler was different from the default installation path. So what I did from then on was to always have the active compiler in a directory named "Drive letter:\Program Files\PICC"
The actual drive letter can be anything.

On switching versions I rename the current compiler directory name to something like "PICC 3.249" and rename the version directory I want to use from "PICC 4.077" --> "PICC"

Crude, but works for me and I'm too lazy to look further into it.

I am using the command line compiler. Tried dumping the compiler in the default folder and still have the same issue.

And you have copied the valid registration files to this directory? (pcb.crg, pcm.crg and/or pch.crg)

I just tried: the registration files you use for v4.xxx are also valid for v3.249 when you copy them to this directory.

No I am not sure if I am using the proper pch.crg file. I have used several versions of the .crg file that I have and all have the same results.

1. Post your version of Windows.

2. What is your version of MPLAB ? (I assume you're using MPLAB).

3. Go to the Configure menu in MPLAB and look at the setting
for the PIC. What PIC is selected ?

4. Go to the Project menu in MPLAB, and then to the Select Language
Toolsuite menu. What is the setting ? Is there more than one
setting available for CCS ? What are they ?

I installed PCH vs. 3.249 and dragged a .c source file onto it.
It works OK for me.

OK here was the issue. In the command line I added +FH. My c files now compile with PCH 3.249.

Kind of funny though. I have never used +FH before this week (I have always left it out and was able to compile with 3.249 or 4.093 with no problems).
