The usual method to install a DB2® product on Windows is to use an Administrator user account. However, DB2 products can be installed using a non-administrator account. To do so, a Windows Administrator must configure the elevated privileges feature in Windows.
This task explains how a Windows Administrator can set up a computer with elevated privileges to allow installation using a non-Administrator user account. The related task of granting DB2 administration authorities to non-Administrator users is also covered.
Typically a Windows Administrator would perform this task to enable another person who does not have an Administrator account to install a DB2 product. The role of this person might be only to install DB2 products or to also administer DB2 products once installed.
An alternative to using the Windows Group Policy Editor is to use regedit.
In the registry branch HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows, add the key installer
In the registry branch HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows, add the key installer
For AlwaysInstallElevated, enter REG_DWORD=1
After you have given elevated privileges, you can reverse this action. To do so, remove the registry key Installer under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows.
At this point, only members of the Windows Administrators group will have DB2 administration authorities. The Windows Administrator has the option to grant one or more DB2 authorities, such as SYSADM, SYSMAINT, or SYSCTRL to the non-Administrator user who installed the DB2 product.
