Hello Alessandro,
First of all, I would like to welcome you to the Forums.
If you want to keep the Registry value type REG_SZ and solve your issue, follow these steps:
1. Go to the side panel in Custom Behavior ->
Search
3. Select the New Search Wizard to create a
Registry Search for your value. Make sure you select to Retrieve the raw value
4. Go to Registry, and create all the required Keys and the value you want to change. Be sure that the value has the same name as the one in your Registry
5. Select the
Replace existing value option, if it is not already
6. In the
Data section of your value put the property of the registry search for example [RESULT_PROPERTY], and afterward write what you want to prepend or append
(example: ValueToPrepend[RESULT_PROPERTY]ValueToAppend)
Note that the value you need to search for needs to be REG_SZ, not REG_MULTI_SZ. So make sure you didn't change the value in your computer's registry with the previous installations.
Let me know if you need any more help.
Best regards,
~Horatiu
