My warm greetings to all,

While I am at work using Microsoft Excel to do my accounting task, an error message appeared on my screen while I am using some add-in, please see below the error message screen shot.

Microsoft Office Excel

Excel experienced a serious problem with the ‘microsoft office live add-in’add-in. If you have seen this message multiple times, you should disable this add-in and check to see if an update is available. Do you want to disable this add-in?

There are times that you instinctively and routinely click the save button in Word and then soon realized that the file you overwritten was the one that you would be needing. How do you go about in retrieving the original file?

My sister keeps on using my desktop and happens to open my Excel files and mess them up. is there a way to protect the file from being opened by putting a password? I know how to protect a sheet but I want a more secured way of protecting my file by not allowing it to be opened in the first place. 

I am working in a psychological testing center in which there are times that I handle sensitive cases. These cases require high level confidentiality and if possible, only a minimum number of people be able to read the reports of these cases.

However, our computers are in a network and the administrator has set it to be accessible by others. Is there a way that I can put a password on the document or file alone and not on the whole folder? 

Hello friends,

Please find the error message screen image generated by the Microsoft Word; I saw this error message while I was trying to open a Microsoft Word document.

Microsoft Office Word can’t start the application required to open this object.

An error occurred and this feature is no longer functioning properly. Would you like to repair this feature now.

Hi guys,

I am posting here an error message that I encountered, I meet this error when I am about to open a Microsoft Word file sent to me via email attachment.

There is insufficient memory or disk space, Word cannot display the requested font.

The error message above gives a lot of headache to me, all that was said on that error I already check, I have a lot of hard drive space and my memory is above the requirements for Microsoft Word, regarding the said font I cannot check it since it was not stated on what is the font name.

Hello to all readers,

I am sharing here my experience for all to comment on.

I had a problem opening my Microsoft Excel file, an error message appeared:

Unable to read file.

I think this problem started when my computer was infected by a lot of virus, but all of it was cleaned by my anti virus application. But after such disinfection I could no longer open my file.

The file is present but cannot be read.

I am now asking for some advices on how to fix this file. All your advices will be of great help to me.

Thanks a lot for reading my post.

Hi to all people,

Please allow me to share my experience here in techyv. When I am about to finish my report using Microsoft Excel it stopped and I met a strange error. Please see below the error message.

Catastrophic failure

As I read on the error, it makes me think twice about such a short error message "Catastrophic failure ". That is why I have a hard time figuring out what went wrong. When I looked for same error message over the internet, none was posted.

I am asking for some help on this error message. Hoping to hear your ideas. Thanks.

Hi friends,

I am consulting here an error I meet while using Microsoft Word in the office over a network file server, I had a problem saving my file to the server, I received an error message that goes There has been a network of file permission error. The network connection may be lost.

There has been a network or file permission error. The network connection may be lost

The error message above is suggesting for a network connection problem, I already check my connection toward the server and its been up and running, when I tried other files I can save it, only this file has a problem.
