Ошибка программы runas не удалось получить пароль пользователя

Добрый день. Проблема такая: По каой-то причине битомет не получает доступ к одному из дисков. При запусе от имени администратора всё в порядке.

По совету в дной из тем тут создал в автозагрузке батник с текстом: 

chcp 1251
runas /savecred /user:Администратор "C:Program FilesBitCometBitComet.exe"
TIMEOUT /T 100 

В итоге она спрашивает пароль, но никак не реагирует на ввод. То есть при вводе букв ничего не происходит, а если попытаться использовать вставку, то выдаёт сообщение о неверном пароле. При этом встроенную учётку админа я включил и запаролил.

ещё заметил, что при попытке сделать то же самое в виндовс павершелл после вставки пароля появляестя ошибка «неверный пароль» и тут же после этого кусок пароля без первых двух букв вставляется как следующая комманда 

PS C:WINDOWSsystem32> runas /savecred /user:Администратор "C:Program FilesBitCometBitComet.exe"

Попытка запуска C:Program FilesBitCometBitComet.exe от имени пользователя "DESKTOP-123Администратор" ...

Введите пароль для Администратор:
Попытка запуска C:Program FilesBitCometBitComet.exe от имени пользователя "DESKTOP-123Администратор" ...

ОШИБКА RUNAS: Не удается запустить - C:Program FilesBitCometBitComet.exe
1326: Неверное имя пользователя или пароль.

PS C:WINDOWSsystem32> 345

При том, что пароль в буфере «12345»

I have tried using the «runas» command from Windows to run a program with lowered credentials than those of the currently active account (in order to «sandbox» that program to be only able to access certain directories and files).
It works fine, for the most part, but I am getting a strange error.
The command that works without any issues is:

runas /noprofile /user:<Username> <program.exe>

But when I try to remove the /noprofile and instead write runas /user:<Username> <program.exe> or alternatively runas /user:<Username> /profile <program.exe> I get an error saying (roughly translated) this:

RUNAS-ERROR: <Path-To-My-Program> cannot be executed
299: Only part of a ReadProcessMemory or WriteProcessMemory request was completed.

I tried researching the error but the only thing I could come across was some people that encountered this error trying to work with CDs, USBs and external hard drives, and setting some registry values for those worked for them.
I did not attempt to modify the registry myself, because I am not using any of these, and thus I concluded that the error had to be something else on my end.

I am really confused as to what is causing this behaviour, and am hoping that someone who is more experienced with this can help me out

Thanks in advance
Best Regards
