How to install 2 copies of the same application
Article Metadata
It may sometimes be useful to install two, or more copies of the same application to the device eg. in case where only minor changes in the source code, or configuration make the application significantly different from the original one.
This may be accomplished in a couple of steps:
1) acquire a new UIDnumber
2) edit the contents of project's MMP file
change the name of target file (it is a good idea to add the UID number, or part of UID number to the file name)
TARGET NewProject.exe
change to
TARGET NewProject_<UID>.exe
where UID is the newly acquired UID number
change the UID3 of the project
UID 0x00000000 <new_uid_number>
change the names of resource files
MyProject.rss
[...]
MyProject_reg.rss
become
MyProject_<UID>.rss
[...]
MyProject_<UID>_reg.rss
in the same way change the name of the MBM file
3) Edit the contents of Package file
- change the UID number of the project
- change the names of all source and target file names eg.
"$(EPOCROOT)Epoc32\release\$(PLATFORM)\$(TARGET)\MyProject.exe" -"!:\sys\bin\MyProject.exe"
becomes
"$(EPOCROOT)Epoc32\release\$(PLATFORM)\$(TARGET)\MyProject_<UID>.exe" -"!:\sys\bin\MyProject_<UID>.exe"
-if applied change the paths of private resources (according to the new UID number)
4) change the names of resource files
- MyProject.rss -> MyProject_<UID>.rss
- MyProject_reg.rss -> MyProject_<UID>_reg.rss
5) change all the #include declarations pointing to the resource files, so that they point to the new names of these files
6) change the name of the generated _aif.mif file name, in the scalable icons make file (Icons_aif_scalable_dc.mk)
ICONTARGETFILENAME=$(TARGETDIR)\MyProject_aif.mif
turns to
ICONTARGETFILENAME=$(TARGETDIR)\MyProject_<UID>_aif.mif
7) If the source files specify the name and location of resource files, MBM or AIF files explicitly, these names also need to be changed
As the last step it may also be helpful to change the caption name of the application, along with other displayed names and other info.

In case if you have a requirement to have the same application installed twice on the same device, you may refer to the tips provided in this article. The author has tried to cover almost all of the changes that needs to be made to the application. Special care needs to be taken that all the UID references in the project are updated to the new UID.
