Revit Based Installation (Ribbon/Toolbar/Location)

Description:

Greyed out options in the Addin Assistant and ribbons do not appear in Revit

Solutions:

1.
Cause:

Installation fails to install the ribbons correctly.

When opening Revit, the HydraCAD, HydraCALC and HydraLIST ribbons do not appear. 

When opening the Add-In Assistant, the options to add / remove them appear grayed out.
Solution: If a Hydratec for Revit install is needed, log into your companies Hydratec ShareFile account and download the latest Hydratec for Revit Install file. You can distinguish the latest file by which has the highest version number. (Example: v23 vs v24, v24 being the latest)
⚠️If you need the permission of your company's IT department, etc. in order to install Hydratec for Revit, contact them before proceeding.


1. Install Hydratec for Revit
    - If you do not have a Hydratec ShareFile account, please follow the link below and select the blue box labeled "Sign Up".
      Hydratec ShareFile Access
    - Information on how to enter Hydratec's ShareFile account or request access can be found here:
      Using Hydratec ShareFile System

2. Once downloaded:
    a. Find the downloaded .zip file
    b. Extract the .zip file to a temporary folder.
    c. Run the Hydratec for Revit setup from the extracted folder, NOT the original .zip file.d. Restart your computer after successful installation.


If after reinstalling, if the ribbons still do not appear, run the Add-In Assistant tool:

1. In file explorer, navigate to the "*<install-drive-letter>\HES\Hydratec for Revit\Programs" folder.
   *<install-drive-letter> should be replaced by the drive letter where you installed Hydratec, most commonly "C:".

2. Locate "HydratecRevitAddinAssistant.exe"

3. Right click the executable, and select "Run as Administrator".
    a. Add any ribbons that are currently missing when loading Revit.
    b. Click "Apply".
    c. If the application does not close, you can close it at this time.

4. Try opening Revit again to see if your ribbon tabs now show up.
    * If the options still remain grayed out, please feel free to contact support at revitsupport@hydracad.com
2.
Cause:

When Add-in Assistant is not working after running, and the HydraCAD Ribbons will still not appear. 
Solution:

Check with your team in charge of security.

They could be blocking one of the folders the Add-in Assistant needs to access. 

The two folders that they will have to check are

  • C:\Users\
  • C:\HES\
