Hi,

The specified folder must contain the following files:
- wampserver.conf
- wampserver.exe
- wampserver.ini
- wampserver.tpl

Is this a brand new installation?

I have seen that after an install, or sometimes an WampServer version upgrade, it is not possible to install some add-ons until after you have started WampServer up at least once.

Not sure if the installer looks for some registry entries that are not created until a startup has been completed, or something similar.

Hi,

Sorry, it's wampamanager, not wampserver!

No need for any other files.

What is the exact and complete error message?

edit: i fixed it
i had to run the exe file and then "restart from zero"
then the installation went through just fine,i normally start services from the "task manager" so i rarely use the exe file.

The test is exactly the same regardless of the add-ons (Apache, PHP, MySQL or MariaDcool smiley and updates.
  Result := '';
  //--- Check if installation folder is that of Wampserver
  if(not FileExists(ExpandConstant('{app}\wampmanager.conf'))
  or not FileExists(ExpandConstant('{app}\wampmanager.exe'))
  or not FileExists(ExpandConstant('{app}\wampmanager.ini'))
  or not FileExists(ExpandConstant('{app}\wampmanager.tpl'))
  ) then
  begin
    Result := ExpandConstant('{cm:NotPreviousInstall}');
    exit;
  end;

I've run into this before! Usually, the addon installer is looking for a specific registry key to find where Wampserver is. If you've moved your wamp64 folder or changed the drive letter, it’ll throw that error. Make sure you're running the addon installer as Administrator and that you've installed the latest Wampserver update (3.3.x) first, as it fixes a lot of the older addon detection issues.
