WUC-19: Unable to write to local file in Windows 7

Problem:

I  can not download the jacob.dll, JNIsharedstubs.dll and D2Kwut60.dll

I’m able to download and save the file on client directly by putting the download in browser, but through application, it gives below errors.

WUC-19: Unable to write to local file
c:\Progra~1\Oracle\Jiniti~1.22\bin\JNIsharedstubs.dll.Failed to download URL
https://xxxxx.xxx.edu.my/forms/webutil/d2kwut60.dll
WUC-19: Unable to write to local file
c:\Progra~1\Oracle\Jiniti~1.22\bin\d2kwut60.dll.
Failed to download URL
https://xxxxx.xxx.edu.my/forms/webutil/d2kwut60.dll

Solution:

Step 1: Drag UAC (User Account Control) vertical slider to minimum

Step 2: Restart the PC

Step 3: Login into your company web database. You will see all the necessary files from the web server will be copied to your local hard disk.

Step 4: You may reset the UAC settings back to the default level. The above files are copied to your local hard disk only once.

ANOTHER SOLUTION: 

Depending on user permissions, you might receive possible errors when accessing a Forms application using Webutil such as:
“WUC-19: Unable to write to local file C:\Program Files (x86\Java\jre6\bin\jacob.dll”
If that is the case, it is recommended to dedicate a directory to where users would have the right to download to. After creating the directory, you will need to do the following:

1. Copy d2kwut60.dll, jacob.dll, and JNIsharedstubs.dll into the directory
2. On the server where you are accessing the Forms application from, open webutil.cfg in a text editor
3. Copy the line “#install.syslib.location.client.1=webutil/syslib” and paste it below. HINT: This line is in the middle of the document.
4. Uncomment the line you pasted
5. Replace webutil/syslib with the full path to the directory where the 3 dlls will be located in.
6. Save all changes in webutil.cfg

After that, you should be able to log into your Forms application without a problem.
