Requirements
These are the requirements of non-root installation on Windows platforms:
Non-Administrator user ID must belong to Power Users group.
VS2005 runtime library must be installed before attempting to install a DB2
product.
Limitations
These are the limitations of non-root installation on Windows platforms:
Services that would be automatically started are run as processes in
non-Administrator installs.
In DB2 Connect, some environment settings must be changed in
HKEY_CURRENT_USER.
After a non-Administrator has installed the DB2, no other user (including
Administrator) can install DB2 on same system. However, the Administrator
can uninstall and reinstall the DB2 product.
Non-Administrator users cannot uninstall a DB2 product.
Further information can be found in the DB2 Information Center:
Table 1-7 summarizes the key differences between root/Administrator
installations and non-root/non-Administrator installations.
