Common installation issues

Let's go over some of the most common issues that people have when using the Adobe Extension Manager to install extension, and how to get around them, or fix them outright.

arrow downUnhide your Library Folder

MAC ONLY

In OS X 10.7, Apple hid the Library Directory from users to help keep inexperienced users from messing around with files they have no business messing around with. Fortunately, there is a way to unhide the folder so we can access the sweet, sweet Dreamweaver Extension files hidden within.

  1. Launch Terminal.
  2. Copy the following code:
    chflags nohidden ~/Library/

  3. Paste the code into Terminal.
  4. Hit Enter and enter your Administrator password if prompted.


If you decide you want your Library directory hidden once more, this can be reversed by doing the following.

  1. Launch Terminal.
  2. Copy the following code:
    chflags hidden ~/Library/

  3. Paste the code into Terminal.
  4. Hit Enter and enter your Administrator password if prompted.

arrow downFixing Common Issues

If installing an extension is taking longer than you would expect, or if you are finding that Dreamweaver is not functioning as expected after installing, you may be able to fix this by deleting the WinFileCache.dat or MacFileCache.dat file.

Follow these instructions to delete this file.

For Windows Users

  1. Close Dreamweaver.
  2. Open a Windows Explorer window.
  3. In the Address bar enter %appdata% and click Enter.
  4. Open the Adobe directory.
  5. Open the Dreamweaver folder for the version of Dreamweaver you are using.
  6. Dreamweaver CS4 users only - open the en_US directory.
  7. Open the Configuration directory.
  8. Locate the WinFileCache.dat file.
    There may be some other numbers appended to this filename.
  9. Press Delete to delete this file.
  10. Open Dreamweaver.
If the problem persists, you may need to uninstall your extensions, reinstall them, then delete the WinFileCache.dat file and open Dreamweaver.


For Mac Users

  1. Close Dreamweaver.
  2. Open your OS X Finder.
  3. Navigate to the following directory:

    Dreamweaver CS4, CS5, CS5.5, CS6
    /users/[username]/Library/Application Support/Adobe/Dreamweaver (version)/en_US/Configuration/

    Dreamweaver CS3
    /users/[username]/Library/Application Support/Adobe/Dreamweaver 9/Configuration/

  4. Locate the MacFileCache.dat file.
    There may be some other numbers appended to this filename.
  5. Press Delete to delete this file.
  6. Open Dreamweaver.
If the problem persists, you may need to uninstall your extensions, reinstall them, then delete the MacFileCache.dat file and open Dreamweaver.

arrow downCommon Alerts

During the installation process, there are three alerts that may appear:

  1. The same version of a file exists
  2. A newer copy of a file exists
  3. An older version of a file exists


When any of these alerts display, you can choose Yes to All to proceed with the installation. This should not cause any problems.

Just bought the suite. Cant install on CC. Double click on the zxp brings me nowhere: there is no extension manager. Calling 1.858.768.6600 all day, only an answering machine. Please, some help on how to proceed? Thanks))

Is there still a strict order to installing the extensions? Previously it caused problems if you did it the wrong way around... ?

Team WebAssist: 3 Years, 6 Months, 1 Week, 5 Days, 22 Hours, 10 Minutes ago

robp295024, If you have the latest version of any/all the extensions, installation order no longer matters. If you have some new and some old versions (like you don't have eCart 6), give Tech Support the versions you have and they'll assist you with your specific scenario.

I used to have Design Extender working just fine. I recently purchased Data Bridge and after installing all I get are errors everywhere. Now nothing works. I uninstalled and re-installed everything I I still get errors popping up all over the screen when I restart Dreamweaver.

Rood's Media, Click HELP to get technical support as we would need to know specific errors, Dreamweaver version, etc. to problem solve.

chiakioda428401: 2 Years, 10 Months, 6 Days, 18 Hours, 18 Minutes ago

since ecart was updated to 6.0.9, I tried to install on DW CC 2014.1 (x64), but I still get the error "DLL.checkSerial is not a function".
Data Bridge has the same error as well. I can not use the products.
Just wondering how long it will take to be fixed...

chiakioda428401: 2 Years, 9 Months, 2 Weeks, 2 Days, 15 Hours, 27 Minutes ago

new version let me enter the serial# but after hitting activate button I get the erroe as follows;
javascript error when executing onmousedown on wadatabridge_ser.htm.
line 1900 on file
C:usersusernameappdata oamingadobedreamweaver cc 2014ja_jpconfigurationsharedwebassistlibrarywa_ui.js".
retVal has no properties

new ecart 6.1 gets the same error as well.

chiakioda428401: 2 Years, 9 Months, 2 Weeks, 2 Days, 12 Hours, 9 Minutes ago

I tried on another machine, this time it says activation number is incorrect when I hit "activation", even when I enter the number it says it is verified and hit activation.
the number is what is given here on my product page and I even cut-paste.

There is no Extension manager in the new Adobe Creative Cloud suite so it's impossible to install this. Please advise...

htm2112: 4 Months, 2 Weeks, 2 Days, 14 Hours, 32 Minutes ago

The Extension Manager has been discontinued by Adobe. Is there an alternate way of installing this extension or is it now considered End of Life?
