One of the most common programs that does this is the Intel Audio Studio.
This solution requires registry modification. So becareful not to change anything else.

1. Go to Start > Run

2. Type regedit and click OK

3. Navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{Program Name}
Note that as the {program name} may be a CLSID, you may need to search for the product name (e.g. “Intel Audio Studio”, using what you saw in Add/Remove) to locate the correct entry.

4. If you see NoRemove with the data 0×00000001 (1), that means the remove button will be unavailable. If you also see NoModify with the data 0×00000001 (1), that means the change button will be unavailable.

5. Simply double click on the NoRemove or NoModify name and change the value data to 0 (number zero). If Add or Remove Programs is open, close it and reopen again. The Change/Remove button should now appear.
