Programs Files vs Program files (x86)

Tomáš123,

You do not have to take any special action when installing applications: 

1. If it is a 64 bit application and your OS is 64 bit then the application's own installation procedure will install it into the Program files folder.
2. If it is a 64 bit application and your OS is 32 bit then the application's installation procedure will fail - a 32 bit OS is not compatible with a 64 bit application.
3. If it is a 32 bit application and your OS is 64 bit then the application's own installation procedure will install it into the Program files (x86) folder.
4. If it is a 32 bit application and your OS is 32 bit then the application's own installation procedure will install it into the Program files folder - 32 bit OSs do not have a Program files (x86) folder.

Applications do not install twice into both the Program files folder and the Program files (x86) folder.  In some cases, 64 bit applications on a 64 bit OS might sometimes create files in both of these folders.  This merely indicates that the 64 bit application has some 32 bit components - it does not mean that it has installed both versions. 

The Program files (x86) folder is for 32 bit applications not 64 bit applications.

You might find that some add-ons [rather then full applications] appear to break these rules but they do not really.  For example [actually, it is the only example I know of] -  

• If you are using the 32 bit version of IE then installing Flash Player would install a 32 bit add-on
• If you are using a 64 bit version of IE then installing Flash Player would install a 64 bit add-on as well 
• This unusual situation is caused by the existence of both 32 & 64 bit versions of IE in 64 bit Windows 7.

• 32 bit application versions will work on both 32 & 64 bit OSs.
• Not all applications have a 64 bit version - these applications are provided as 32 bit applications for use on both 32 & 64 bit OSs.
• If a 64 bit version of the application exists then it will be able to take advantage of the increased processing power & memory-handling capability of a 64 bit OS and will run faster then its 32 bit version.
• Applications might be supplied in both 32 and 64 bit versions so you simply have to choose the correct one.  If the application does not tell you whether it is 32 or 64 bit then it is probably 32 bit.  If you accidentally choose the 64 bit version but your OS is 32 bit then the installation will fail.
• An increasing number of applications have a single installation file that checks your OS then installs the correct version [into the correct folder].

i don't know what it is ?Think you know that.I never can be4 here on yje laptop ore it crashed,mine facebook game landleven.nl never does it good

They say new flash player have trough off new onn an same do again.If i starded lapyop Need to click on enter that whas when i get him from mine husband second nand .

Write me if you want to now some i hope when i go in februat 9 weakes for revalidation?

Thank you very much for this answer. :-)

32bit operating systems are not compatible with 64bit programs.
