Modify the Workstation Registry

To run the erwin 32-bit API in a 64-bit environment you must modify the workstation registry.

Follow these steps:

1. Copy the following code and paste it to a new Notepad file:

   Windows Registry Editor Version 5.00
   [HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{9527D0BA-ED75-4b0e-BF4B-E35565DE9852}]
   @="erwin Data Modeler Script Client API"
   "AppID"="{9527D0BA-ED75-4b0e-BF4B-E35565DE9852}"
   [HKEY_CLASSES_ROOT\Wow6432Node\AppID\{9527D0BA-ED75-4b0e-BF4B-E35565DE9852}]
   "DllSurrogate"=""
   [HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{40FDB0E6-D772-455d-B1C8-83CE79445403}]
   @="erwin Data Modeler Script Client API Property Bag"
   "AppID"="{40FDB0E6-D772-455d-B1C8-83CE79445403}"
   [HKEY_CLASSES_ROOT\Wow6432Node\AppID\{40FDB0E6-D772-455d-B1C8-83CE79445403}]
   "DllSurrogate"=""
   [HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{6774E2C3-06E9-4943-A8D4-E3007AB1F42E}]
   @="erwin Data Modeler Script Client API"
   "AppID"="{6774E2C3-06E9-4943-A8D4-E3007AB1F42E}"
   [HKEY_CLASSES_ROOT\Wow6432Node\AppID\{6774E2C3-06E9-4943-A8D4-E3007AB1F42E}]
   "DllSurrogate"=""
   [HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{7D7B1602-9832-4ac6-A224-F0092FAF0D7E}]
   @="erwin Data Modeler Script Client API Property Bag"
   "APPID"="{7D7B1602-9832-4ac6-A224-F0092FAF0D7E}"
   [HKEY_CLASSES_ROOT\Wow6432Node\AppID\{7D7B1602-9832-4ac6-A224-F0092FAF0D7E}]
   "DllSurrogate"=""
   [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{9527D0BA-ED75-4b0e-BF4B-E35565DE9852}]
   [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{40FDB0E6-D772-455d-B1C8-83CE79445403}]
   [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{6774E2C3-06E9-4943-A8D4-E3007AB1F42E}]
   [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{7D7B1602-9832-4ac6-A224-F0092FAF0D7E}]
   

2. Name the Notepad file as 64_Bit_Upgrade.reg. Note down the folder where you have created this file.
3. After installing erwin DM version 9.0.0 through 2018 R1, right-click 64_Bit_Upgrade.reg and select Merge.
4. From the Windows Start menu, go to Run and type the following commands to re-register the EAL components:

   regsvr32.exe  "<Install Dir>\erwin\ Data Modeler r9\EAL.dll" 
   

   regsvr32.exe  "<Install Dir>\erwin\ Data Modeler r9\Upgrade\R8_Binaries\EAL.dll".
   

5. Right-click 64_Bit_Upgrade.reg and select Merge again.

   You can now run erwin 32-bit API in a 64-bit environment.
