Hi Cservice,
a) Which application are you trying to install?
You may search the Windows registry for the invalid character that is displayed in the 1324 error message and replace all instances of the invalid character with the correct character. For example, if the 1324 error message refers to "system32/", you should search for "system32/". If you find any instances in the registry, modify them, so that the registry values correctly reference the System32 folder.
- Click Start, and then click Run. In the Open box, type regedit, and then click OK.
- On the Edit menu, click Find.
- In the Find What box, type the character string reported in the 1324 error message, and then click Find Next.
- If you find the problematic string, make any necessary changes, and then press F3 to find the next occurrence.
- Repeat step 4 until you locate and change all incorrect references.
- On the Registry menu, click Exit.
Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
