Backup all of the files in your BOINC folder to a safe location.
This is commonly C:\Program Files\BOINC\
I normally like to use Winrar & just compress everything so I have C:\Program files\BOINC.rar
|Step 2)||Install BOINC 6.12.xx over your current installation.|
Stop BOINC & restore boincmgr.exe & boinc.dll from the old version
For many system you can place the old boincmgr.exe & boinc.dll in your current folder & everything will be fine.
If so you are done
If BOINC Manager does want to run you might need a few extra files & steps.
I found on a few older XP x86 systems I needed to do this.
You may also need the older version of Microsoft.VC80.CRT.manifest, msvcm80.dll, msvcp80.dll, msvcm80.dll, & sqlite3.dll.
Place these files in a seperate folder. I used BOINC\BM
A copy of your gui_rpc_auth.cfg will need to be place in this folder as well if you are using one.
Also I removed C:\Program Files\BOINC\boincmgr.exe so I would not run it by accident.
Make a batch file to start everthing for you. I called mine boinc_go.bat but you can use whatever you like.
This is an example of the files I use.
start BM\boincmgr.exe /s
