..depending on your version of Word.

I would prefer guide below or another methods are proposed from different sources over Internet, but in case the guide from MS Corporation can't handle the problem

1. Open PowerPoint 2007.
2. Click the Microsoft Office Button and click Open.
3. In the File name: box, enter the text in bold to display a list of the automatically saved files (if any).You can also copy and paste this text into the File name: box.
   
   PowerPoint 2007: %temp%\ppt*.tmp
   
4. Click the Open button.
5. Click the name of the file that you want to recover, and then click Open.
   
   Note : The automatically saved files may not be named in a descriptive way. Continue to open files until you find the one you are looking for.
6. After you find the file, click Save. Then save the file to your My Documents or other location.

To fix it, put in your Office 2003 or Office 2007 CD into your drive and wait for the setup program to start. If it doesn't start automatically, find the Setup.exe file on the CD and run it manually. Once the setup window appears, just click Cancel. Click OK to whatever prompts come up after you click Cancel.
That's it! Loading the setup screen fixes the corrupt setup files and allows you to open an Office program without the 25090 error!

I am hoping that you meant "windows 7" and not windows 8, as there is no such thing as windows 8, only windows 7 premature builds.
You could never connect to the internet via desktop. Mozilla firefox is an internet browser, just as microsoft internet explorer is an internet browser.
You can configure which browser is automatically brought up by opening internet explorer (Start>Internet Explorer) and selecting "use this browser as my default browser".

install interne explorer from this linke or try some other browser like chrom, firfox...

You need to open these files with a newer version of Word.

I use a program called OpenOffice

www.openoffice.org

It's a free open-source version of Microsoft Office and can open docx files.

Good luck!

It is the way you are saving them once scanned. Set the default scan to save as PDF files.

Hello, you are probably using an incorrect connection string.

Usually you can use a datasource (such as Access Database) directly in an excel document. If that is what you are trying to accomplish here check out the following sites:
Plug into your data Connecting Excel to an Access database Office Blogs
OR:
Connect an Access database to your workbook

If you are writing software application, from within Visual Studio (depending on the version) go to the left-hand side bar to "Server Explorer" -> "Add Data Connection" -> Click on the "Change" button of the Data Source part and select the appropriate Access Data Source -> Click the "Advanced" button.

After that, you will see in the bottom textbox, the appropriate connection string for the JET.OLEDB Connection Provider.

This is shown in the image below:

Alternatively, you can find more information about your connectivity string in the link below:

For usage of an oledb connection object you can find info here --> https://msdn.microsoft.com/en-us/library/system.data.oledb.oledbconnection(v=vs.110).aspx

Check TOOLS --> OPTIONS on the SAVE tab. See if "always make a backup copy" is checked.
