Some questions and answers :
1) If I select Hindi language, I cannot enter details in Hindi with my English keyboard.
I am unable to understand whether you do not know Hindi typing or the DataForm is refusing to accept any input made by you. If the latter is your problem, then the installation was defective, for which you should read :

English and Hindi modes have different datafiles. In my own computer, English mode has only 80 records, while Hindi mode has a large number of records. In Hindi mode, "Vinay Gakkhar" will be written as "fou; xD[kj" if you use fonts according to standard typerwriter styed keyboard layout (but differently if you use Hindi Unicode fonts designed for internet). What you want is automatic transliteration of Hindi entry into English and vice versa. These user friendly features may be attempted after I finish the main programming. I do not have a team, I am doing all this single-handedly.
3) Despite selecting English language, the charts details are being displayed in Hindi.
English version has more essential files in English, and comparatively less important files are yet to be translated, which you should not view if you do not know Hindi. It will take time to translate the entire program.
4) Chart details of Varshphal are not displayed, I see the following message : "Run-type error '13'; type mismatch"
If this problem occurs always then installation was defective. Before concluding, close and restart the program. Opening many files at once may cause problems sometimes. If this problem occurs only for a particular native, send me the birthdata for that native.
In future, please try to be more clear and specific.
