NEW YORK (CNN/Money) - Royal Bank of Canada, the country's largest bank, said Friday it has fixed a computer glitch that has affected many of its customers in the past week and its bank account operations should return to normal this weekend.

A technical problem that started on May 31 prevented client transactions, such as deposits, withdrawals and payments, from showing up in account balances.

The glitch was fixed Tuesday, but a huge backlog in verifying transactions has caused a delay in adjusting account balances, a spokeswoman for Royal Bank said on Friday.

"We have fixed the root of the problem, but now we're trying to update the system," said Judi Levita, a spokeswoman for RBC. "We are keeping many of our branches open this weekend to help customers affected by this."

RBC has about 10 million banking clients in Canada and processes about 10 million transactions a day, Levita told CNN/Money.

The bank said the problem had not affected customers outside of Canada.
