F＃Excel-新ApplicationClass上的错误

Question

When I do just

type RExcel() = 
    let xlApp = new ApplicationClass()

I've got this Error :

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Класс не зарегистрирован (Class doesn'registered) (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

So maybe I can realize Excel read/write functions some another way.

Added : installed OpenOffice... Version of assembler is 14 ... Maybe I need to use some another .NET library for Excel ?

I'm not sure I correctly understand your scenario, but if you want to call Excep using ApplicationClass , you need to have full Excel installed on your machine (and all users of your application will need to install Excel too). The library is just a wrapper that calls some internal functionality in Excel.

If you want to generate Excel files in F# directly, you can take a look at libraries that generate XLSX (new XML-based format) files. For example: http://epplus.codeplex.com/ This should be easy to use from F# and should not have any other requirements.
